Dear krose_87,
Good day!
Based on your description, it seems like you’re experiencing an issue where a previously deleted channel in Microsoft Teams has reappeared.
If the channel was recently deleted, it might still be in this retention period. If you want to clean up all objects of a channel, you need to delete it from Teams and then remove any other content associated with the channel manually after the retention period.
To get a better idea on your scenario, could you please share with me a screenshot of the deleted channel saw by other members? May I please know if other members can still see the deleted channel on Teams Web?
Thank you for your precious time and cooperation.
Sincerely,
Hailey Wang | Microsoft Community Moderator
